Abstract

The increasing complexity and shorter life cycle of software have made it necessary to reuse software. Object-oriented development had not provided extensive reuse and computing infrastructures are evolving from mainframe to distributed environments. However, components provide more advanced means of structuring, describing and developing system, because they are more coarse-grained and have more domain-specific aspects than objects. And they are also suited for distributed environment due to their reusability and granularity. In this paper, we present a process including the static metrics and guidelines that can be applied to transform object-oriented systems into component-based systems. Our process consists of two parts: First, basic components are created based upon composition and inheritance relationships between classes. Second, intermediate system is refined into component-based system with the static metrics and guidelines we propose.

점차적으로 소프트웨어의 복잡도는 높아지고 그 생명주기는 짧아지므로, 기존의 검증된 소프트웨어 요소를 재사용 하는 것이 필요하다. 그러나 기존의 객체 지향 기술은 광범위한 재사용을 유도하지 못 하였다. 컴포넌트는 객체보다 규모가 크고 특정 도메인에 적합한 특성을 가지므로, 시스템 구조화, 설명 및 개발에 있어 더 나은 수단을 제공해 준다. 또한 그 규모나 재사용성에 있어 새로운 개발환경인 분산 시스템에 더 적합하다. 본 논문에서는 객체지향 시스템을 컴포넌트 기반 시스템으로 변환하는 프로세스를 제안하였다. 해당 프로세스는 두 단계로 나뉜다. 우선, 클래스들 간의 합성 및 상속 관계를 이용하여 기본 컴포넌트를 생성한다. 그 후 기본 컴포넌트와 컴포넌트화 되지 않은 클래스들에 대해 본 논문에서 제안된 정적 메트릭과 가이드라인을 이용하여 정제하여 컴포넌트 기란 시스템으로 변환한다.
